T a/ZZ whomjt may concern:

Be it known that I, EDWARD HENRY has for `its object to provide a simple, inexpensive, and eicient lconstruction and arrangement of parts capableof adjustment to suitthe width and length of sacks of different dimensions, the `means Afor engaging the sack-mouth being devoid of spurs or points `to avoid injury to the receptacle and the construction of the stretcher being such as to adapt it to be adjusted and secured by a single movement of the operator.

Further objects and' advantages of this inventiou will appear in the following description,` and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure lis a perspective view of a sack-holder constructed in accordance with my invention, a sack being shown in operative position thereon. Fig. 2 is a plan View, partly in section, the sack beingomitted to shw the construction of the stretcher. Fig.

3 is a vertical section taken in the plane of one of the standards. Fig. 4 is a central seeytional view of the base and contiguous portions of the apparatus to show the means for disengaging the adjustable members of the standards. Fig.5 is a bottom plan view of the base.

Similar numerals of reference indicate corresponding parts in all the figures of the drawnected at their upper ends by an integral and depressed vto arrange said cross-bar in av cross-bar 4 to form la vertically-adjustable frame, the upper ends of the movable members of the standard being curvedv laterally plane lower than the contiguous portions of the movable members. The movable'men- .bers Sand the cross-bar by which they are connected may be constructed of a single ban of` the standards are provided with ratchetteeth 5 for engagement by locking-pawls 6, having actuating-springs 7, whereby-When the movable members are elevated they are secured at the desired adjustment by the engagement of said pawls with/ the ratchetteeth. f

The means illustrated in the drawings for disengagingthe pawls to allow the adjustable frame to be lowered include atrip-bar 8,. ex-

of metal, as shown. 'The movable members tending longitudinally of the base and connected terminally Withthe lower extremities of links 9,attached,respectively,to said pawls,

the links being provided in their lower ends with eyes-10 to `receive the reduced extremities of the trip-bar, and treadles or trip-levers 111 and 12, looselymounted for vertical movement upon the under side of the base and extending at intermediate points across the tripbar, whereby the depression of the outer extremity of either trip-lever is adapted to debers of the standards. The trip-levers extend, respectively,beyondopposite side edges of the base, as shown in Figs. 3 and 4,'and the counection thereof with the .base is formed by means of bolts 13. v l

The-vertically-adj ustable su pporting-frame carries a stretcher 14, adapted to. engage the 'mouth of a sack to distend [the same to facili-4 tate the introduction of the material to be packed, and in practice I prefer to construct said stretcher of relatively-adjustable armed members 14a and 14h, the arms of whichare arranged in parallel planes, and those of the member 14a being tubular to receive those of the member 14, as shown clearly in Fig. 2.- rlhe sack is arranged at its 'open end within this stretcher and is then folded outwardly at its edge to extend slightly below the planegof the stretcher, after which the relative outward adjustment1 of the stretcher members serves to firmly secure the sack iu place without injury to the material thereof, inasmuch as all necessity for spurs or points to engage thev sack'is avoided. The vstretcher as above lconstructed lis mounted upon the supportingframe by means of stems or shankslsecured,

respectively, to the ends of the stretcherguides 16 on the adj ustablev members of the standards, and the adjustment of said stretcher members is facilitated by means of operating-levers 17, fulcrumed at their lower ends` upon collars 18, mounted to slide upon the fixed members .of the standards and connected at intermediate points to the outer extremities of said stems or Shanks. In `the drawings the operating-levers are shown provided with openings through which said stems or shanks extend, anddisplacement thereof is prevented by means of pins or studs 19, arranged, respectively, upon opposite sides of the plane of each lever. It is obvious that as the adjustable frame is moved vertically the operating-levers will follow the movements thereof, said collars, upon which the operating-levers are fnlcrumed, being free to slide upon the fixed members of the standards.

vAfter the operating-levers, or one of them,l

have been adjusted to properly stretch the mouth of the sack they are held in the desired positions by means of locking-pawls 20, fulcrumed upon the movable members of the standards and adapted at their free ends to engage ratchet-teeth 2l on said lever, each pawl being provided with a stop-ear 22 t0 limit its swingingmovement in the opposite orinward direetion,and said pawls being preferably mounted for extension by gravity.4 Also in connection with the stems or shanks of the stretcher members I preferably employ set-screws 23, mounted in the guides of said stems or Shanks and adapted to impinge terminally upon the same to lock the stretcher members, or one of them, at the desired adjustment. The advantagebf this construction resides in the fact that one of the stretcher members may be locked in a given position, while the other is left free for adjustment in order to engage an'd disengage the mouth of a sack or a series of sacks. The amount of movement of one member of the stretcher is suicient to accomplish said engagement and disengagement, and hence the operation of engaging and disengaging a sack is simplified by leaving only one member of the stretcher free. In other words, the stretcher may be adjusted approximately to the size of the mouth of the sack when a number of sacks of a uniform size are to be filled successively, after which the successive engagement and disengagement of the sacks may be accomplished by the manipulation of a single operating-lever, whereby it may be attained wholly by one hand'of the operator.

From the above description it will be seen that a sack of any ordinary dimensions may 'after which if it is desired to tie the'sack be engaged and stretched at its mouth by means of the mechanism provided for that purpose, after which the movableframe may be adjusted to allow the bottom of the sack tojust touch the upper surface of the base. After the sack has been filled it may be released by disengaging one of the operatinglevers to allow the sack t0 rest upon the base,

before removing it from the apparatus the `movable frame may be elevated to remove the stretcher suiciently to enable said operation to be performed. When it is desired to lower the adjustable frame, it is accomplished by grasping the cross-bar or the curved upper extremities of the movable members of the standards and at the same time depressing the adjacent trip-lever or treadle to release said frame, after which the frame may be lowered to the desired' point.

Furthermore, it is frequently desirable to employa measuring device in connection with the operation of filling a sack or of partially filling ythe same, and the cross-bar et, which is located above the plane of the stretcher, forms a convenient guard or rest to support such a measure in convenient position, said crossbar being arranged at one side of the stretcher, whereby the supported sack may be readily filled by means of a shovel at the side opposite to the cross-bars.

' Cross-sectionally-round bars are employed for the sections of the stretcher in order to allow the sack, which extends upwardly within the stretcher, to fold outwardly around said stretcher bars or rods, with the edge thereof under or below the plane of the same, the sack being usually constructed with a folded or selvage or thickened edge, which yields less readily under the outward strain of the stretcher than the portion ofthe sack contiguous thereto. Hence when the stretcher is adjusted the thickened edge of the sack `causes it to have a contracting effect below the plane of the stretcher Aand securely lock the sack against displacement during the filling operation.

Various changes inthe form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
